Hi,
I had a quick look and indeed Geoserver is not able to open the files, I
see errors like:
Caused by: org.geotools.data.DataSourceException: java.io.IOException:

According to the documentation
<https://docs.geoserver.org/stable/en/user/extensions/netcdf/netcdf.html#notes-on-supported-netcdfs>,
GeoServer should be able to open files conforming to the COARDS
<https://geos-chem.readthedocs.io/en/latest/geos-chem-shared-docs/supplemental-guides/coards-guide.html>
convention...
checking the files with PanoplyJ I see a grouping/netsting construct I
haven't seen before, which does not seem to appear
in COARDS either:

It might be possible to have GeoServer open these files, but I guess that
would need some code
<https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-fixes,-improvements-and-new-features-in-GeoServer>
modifications in the NetCDF driver
<https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-fixes,-improvements-and-new-features-in-GeoServer>
.
Cheers
Andrea
